The study aimed to study the structure of the Earth’s crust in oceanic areas using pressure signals from the ocean. The study used ocean bottom stations (OBS) to measure seafloor deformation and pressure signals and preprocessed the data to remove earthquakes, glitches, and tilt noise caused by deep ocean currents. The compliance function was calculated by combining pressure and displacement data and is sensitive to regions with low shear velocity. The study used data from the French OBS of the Rhum-Rum experiment near La Reunion Island for 13 months in 2012, and the crustal shear velocity structure below each station was recovered by depth inversion of compliance.
